Bottom stirring

Bottom stirring with inert gas (Ar/N2) serves to improve the homogenization of the bath. The bath/slag reaction is enhanced and conditions close to the thermodynamic equilibrium can be reached.

Highlights

  • Flow rate and type of stirring gas adapted to process phase and steel grade
  • Optimization of blowing process
  • Minimization of inert gas consumption by low flow control
  • Alternating stirring as add-on available

Benefits

  • Increased yield
  • Good metal homogeneity
  • Reduced material consumption
  • Low final carbon content at lower final oxygen level
  • Lower FeO content in the slag
  • Possibility of N2 alloying with N2 stirring gas
